lSPECIFICATION forming part ot Letters Patent No. 252,357, dated January17, 1882,

i Application filed September 12, 1881. (No model.)

Beit known that I, JENNIE R. CooPER, a citizen ofthe UnitedStates,residing at Union City, in the county of Erie and State of Penn-Sylvania, have invented new and useful im- Vforlubricatingthejournalsofcar axles in which the oil is conveyed from the reservoir to the 15`journal byaroller which is in frictional contact with the journal, andis thereby revolved and is also partially immersed in the oil in thereservoir, and by thus revolving whileso immersed conveys the oil fromthe reservoir to the journal.

My invention consists in providing.,r 'such an apparatus with certainimprovements in construction and operation, as is hereinafter fullydescribed, and designated by the claims.

My invention is illustrated in the accompanying drawings as followsFigure l is al longitudinal section taken on the line 1 l in Fig. 2.Fig. 2 is a transverse vertical section taken on the line 2 2 in Figi.Fig. 3 is a top or plan view of the oil-reservoir and conveying-roller.Fig. 4 is a perspective viewT of said reservoir with the roller removed.Fig. 5 is a perspective view, on a larger scale than the foregoing, ofthe said reservoir, with partsbroken oi, so` as to show internalconstruction. This view also showsthe roller in place. Fig.6 is alongitudinal vertical section ot' the oil-reservoir on the same scaleasin Fig. 3, and shows also an alternative construction of the springsupporting the roller. Fig. 7 is a perspective view of the spring whichis shown in Fig. 6.

The parts shown in the drawings are designated by letters of referenceas follows:

A represents an ordinary car-axle box, A',

the cover to the same. Bis the car-axle proper, and C the journal of thesaine. I) is the oilreservoir,which is a metallic box or bowl,sep

arate and distinctfrom the box A, and sets Within the saine below thejournal C. it is divided into two partsa reservoirchamber and a hopperor dishing top. f E is the roller; e e,

the journals ofthe roller ;ff, the springs supporting the roller inproperposition. ffare i the alternative/forms of springs for supportingthe roller. g gg g are guides for keeping the roller in proper positionvertically. dtd

are lugs for keeping the springs ffin proper in place by verticalguides, and sustaining it" in Contact with the journalbyspriugs, towhich the roller is journaled; third, making the oilreservoir a separateand detachable vessel, and providing it with a hopper-shaped top forcatching the drippings of oil from the journal.

The construction and arrangement of parts are as follows: i

First, ofthe roller. I aml aware that rollers of various constructionhave heretofore been used for the purpose herein shown.. My deviceconsists of a roller having tufts ot' bristles arranged upon its body,as shown in Figs. l and 3. The object of this construction is tofacilitate the operation of conveying the oil to thejournal. Thebristles should not be very long, and should be as stift' as possible.However, to insure the rotation of the roller when the bristles becometoo pliable, the roller or its shaft or journal may be provided with abearing-surface of wood, metal, or any hard substance, which will be soarranged as to come in direct frictional contact with the journal oftheaxle. Such a construction is shown in Fig.1 and marked E.

Second. The devices for keeping the roller in place vertically andkeeping it in frictional contact with the journal of the axle are asfol` lows: These devices, in other word-s, constitute the hangings oftheroller. Lugsg g g gat the ends ofthe openingin thetop oftheoil-reservoir form `guides for thejournals ot' the roller, permittingvertical movement of the roller, but preventing lateral movement.supported by a wire, j', at each end, which is bent so as to form aspring and Ialso a journal-bearing for the roller. These are shownclearly in Figs. 2 and 5. In Figs. 6 and 7 an alternative constructionis shown tor the spring. The feet of the springs frest upon the bottomof the oil-reservoir, and are kept in place by The roller is guides d',which are lugs east on the bottom of the reservoir. These devices forhanging the roller maybe used for any kind ot' a. roller, Whether plainor prepared with bristles cr covered with felt or other absorbent.

Third. The oil-reservoir D is made with an oil-compartment, d, and witha Haring hoppershaped top. The opening between the two is occupied bytheroller The wholedeviee is made so as to be set into the axle-box A, asshown in Figs. 1 andf2, and may be taken out for cleaning and repair atany time. It may be made ot' cast metal, all in one piece, or'of sheetmetal, such as tin, if desired. The hopper-shaped top Bares out andreaches up bythe side of the axle-journal C, so as to catch thespatterings and drippings ot' the oil.

The exact form of parts, as shown, is not strictly essential, as theymay be varied without affecting the object and purposes sought by myinvention.

What I claim as new is as follows:

1. In a car-axle-lubricating devioe,the oilconveying roller provided onits surface with tibrousand absorbent material, and a tractionsurfaee,E', in direct contact with the axles, substantially as and for thepurposes set forth.

2. In a car-aXle-lyubrieating device, the combination, with the journalofthe oil-conveying roller, of the vertical guides g g,supportingspringf, haring its feet resting upon the reservoir tloor orbottom, and the guides d, located, as shown, to prevent the feet ofspringf from slipping laterally, all combined and arranged substantiallyas described.

3. An oilreservoir for car-aXle-lubrieating de\"iees,having` a hoppershaped top forcatching` the drippings, vertical guides for the journalsof a roller, 'and lateral guides upon the floor, for the purposesettorth, in combination with aroller haviugsprings attached tothejonrnal and resting upon the door between the side walls and lateralguides, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand thisSth day of September, 1881.
